Abstract

The distribution, thickness and composition of the floodplain sediments in the valleys of the Aar and its tributaries (Taunus Mountains) were investigated by way of extensive fieldwork at 25 locations. In the entire catchment area, 48.8 million tons of loamy f loodplain fines could be assessed. Most of these were deposited since late medieval times due to extensive historical land use and forest clearing, especially in the mining region along the middle course of the Aar. In its lower course, the enhanced sedimentation of loamy f loodplain sediments started during the Bronze Age.

Abstract

High-resolution sedimentological and geochronological investigations of paleochannel systems in the Ried Central d'Alsace (northeastern France) allow for the reconstruction of the late glacial and Holocene fluvial evolution of this section of the Upper Rhine alluvial plain. During the Oldest Dryas, the landscape featured a dominant braided Rhine system and, to a lesser extent, a braided Fecht system. The shift to the Bølling-Allerød saw a narrowing of the Rhine's active channel belt, the development of a complex channel pattern, and the genesis of the Ill River. The river channel patterns remained unchanged during the Younger Dryas. In the Early Holocene, the Rhine's active belt narrowed further, and the Rhine and Ill Rivers developed braided-anastomosing and anastomosing channel patterns, respectively. Throughout the Holocene, both rivers maintained their channel patterns while migrating east and west across the alluvial plain, respectively. In the late glacial, fluvial dynamics in this section of the Upper Rhine plain were primarily influenced by climate-related environmental and hydrogeomorphological changes. Conversely, during the Holocene, the evolution of the fluvial hydrosystems was driven by a complex interaction of climatic and non-climatic factors, including human activity at the catchment scale, alluvial plain architecture, and local neotectonics.

Abstract

Beryllium-10 cosmic-ray exposure (CRE) dating has revolutionized our understanding of glacier fluctuations around the globe. A key prerequisite for the successful application of this dating method is the determination of regional production rates of in situ accumulated 10 Be, usually inferred at independently dated calibration sites. Until now, no calibration site has been available for the mid-elevation mountain ranges of central Europe. We fill this gap by determining in situ 10 Be concentrations in large boulders on moraines and by applying radiocarbon and infrared-stimulated luminescence (IRSL) dating to stratigraphically younger lake sediments in the southern Black Forest, SW Germany. The dating methods yielded concordant results, and, based on age–depth modelling with 14 C ages, the age of a cryptotephra, and IRSL ages, we deduced a regional 10 Be production rate in quartz. Calibrating the Black Forest production rate (BFPR) in the Cosmic-Ray Exposure program (CREp) resulted in a spallogenic sea-level and high-latitude (SLHL) production rate of 3.64±0.11 atoms 10 Be g -1 quartz a -1 when referring to time-dependent Lal–Stone scaling, the European Reanalysis (ERA)-40 atmosphere model, and the atmospheric 10 Be-based geomagnetic database in CREp. The BFPR turned out to be ∼11 % lower than both those at the nearest calibration site in the Alps (4.10±0.10 atoms 10 Be g -1 quartz a -1 at SLHL) and the canonical global 10 Be production rate (4.11±0.19 atoms 10 Be g -1 quartz a -1 at SLHL) in CREp. A stronger weathering and snow cover bias and a higher impact of forest, soil, moss, and shrub cover at the study site likely explain this discrepancy. [ABSTRACT FROM AUTHOR]

Abstract

Beryllium-10 cosmic-ray (CRE) exposure dating has revolutionised our understanding of glacier fluctuations around the globe. A key prerequisite for the successful application of this dating method is a thorough understanding of local production rates of in-situ accumulated 10Be, usually inferred from independently dated regional reference sites. For the mid-elevation (Variscan) mountain ranges of central Europe, no production rate reference site has been available so far. We fill this gap by determining in-situ 10Be concentrations in large boulders on moraines and by applying radiocarbon and luminescence dating to stratigraphically younger lake sediments in the southern Black Forest, SW Germany. The dating methods yielded concordant results and, based on age-depth modelling with 14C ages, we deduced a local 10Be production rate. The resulting Black Forest (BF) production rate is ~11 % lower than both those at the nearest reference site in the Alps and the canonical global 10Be production rate. A stronger weathering and snow cover bias and a higher impact of soil, moss and shrub cover at the stud site likely explain this discrepancy. Due to its internal robustness, we suggest applying the BF production rate in future CRE dating studies in Central Europe and for revising existing age estimates which will have crucial implications for understanding past atmospheric circulation patterns.

Abstract

Sedimentary records from the Kumtag (also known as Kumtagh) Desert (KMD) in northwestern China are investigated to better understand Late Quaternary paleoenvironmental changes in this hyper-arid region. Presented here are the results of probably the first systematic survey of sedimentary sequences from the KMD, with the chronology determined by the optically stimulated luminescence dating. The variation of sedimentary facies, supported by granular and geochemical paleoenvironmental proxies, is used to decipher the history of Late Quaternary environment changes. The results demonstrate that a constantly dry condition characterized the eastern KMD since the last glacial maximum, but with occurrences of wetter periods. From ca. 17 to 15 ka, fluvial activity was probably triggered by melting of glaciers in mountains located south of the KMD. A distinctly drier stage (ca. 13-7 ka) was recognized due to the prominent occurrence of aeolian sands. A wetter environment likely persisted between ca. 4.4 and 2.2 ka, consistent with evidence of human activities. While the causes of paleoenvironmental changes in the eastern KMD are still a matter of debate, the melting of glaciers in the Altyn-Tagh Mountains in the south must be considered as an important factor.

Abstract

Loess–palaeosol sequences (LPSs) are key archives for the reconstruction of Quaternary environmental conditions, but there is a lack of investigated records from the southern Upper Rhine Graben (southwestern Germany). To close this gap, a LPS at Bahlingen-Schönenberg was investigated at high resolution using a multi-method approach. Infrared stimulated luminescence screening reveals a major hiatus in the lower part of the LPS that according to luminescence dating is older than marine isotope stage (MIS) 4. The section above the hiatus formed by quasi-continuous loess sedimentation between ca. 34 and 27 ka, interrupted by phases of weak reductive pedogenesis. The fact that this pedogenesis is much weaker compared to corresponding horizons in the more northerly part of the Upper Rhine Graben could be due to regionally drier conditions caused by a different atmospheric circulation pattern at the time of deposition. Our results reinforce earlier notions that the major environmental shifts leading into the Last Glacial Maximum (LGM) of southern Central Europe significantly predate the transition of MIS 3 to 2 (ca. 29 ka). In particular, the last massive phase of loess accumulation started several thousand years prior to the arrival of glaciers in the foreland of the Alps, which raises questions regarding the source and transport paths of the dust. It is also noted that no loess dating to the LGM or the time thereafter was observed due to either a lack of deposition or later erosion., Löss-Paläoboden Sequenzen (LPS) sind Schlüsselarchive für die Rekonstruktion von quartären Umweltbedingungen, aber es mangelt an der Untersuchung solcher Abfolgen aus dem südlichen Oberrheingraben. Um diese Lücke zu schließen, wurde eine LPS bei Bahlingen-Schönenberg mit einem multimethodischen Ansatz hochauflösend untersucht. Die Untersuchung mit Infrarot Stimulierter Lumineszenz Screening zeigt einen Hiatus im unteren Teil der LPS, der laut Lumineszenzdatierungen älter ist als das Marine Isotopenstadium (MIS) 4. Der Abschnitt oberhalb des Hiatus bildete sich durch quasi-kontinuierliche Lössablagerung zwischen ca. 34 und 27 ka, unterbrochen von Phasen schwacher reduktiver Pedogenese. Da die Pedogenese im Vergleich zu entsprechenden Horizonten im nördlicheren Teil des Oberrheingrabens viel schwächer ausgeprägt ist, könnte dies auf regional trockenere Bedingungen zurückzuführen sein, verursacht durch ein anderes atmosphärisches Zirkulationsmuster zur Zeit der Ablagerung. Unsere Ergebnisse bestätigen frühere Annahmen, dass die großen Umweltveränderungen, die zum letzten glazialen Maximum (LGM) im südlichen Mitteleuropa führten, deutlich vor dem Übergang von MIS 3 zu 2 (ca. 29 ka) lagen. Insbesondere begann die letzte massive Phase der Lössakkumulation mehrere tausend Jahre vor der Ankunft der Gletscher im Alpenvorland, was Fragen zu den Quellen und Transportwegen des Staubs aufwirft. Es ist auch festzustellen, dass kein Löss aus dem LGM oder der Zeit danach gefunden wurde, entweder aufgrund fehlender Ablagerung oder späterer Erosion.

Abstract

Quaternary environments on the Arabian Peninsula shifted between pronounced arid conditions and phases of increased rainfall, which had a profound impact on Earth surface processes. However, while aeolian sediment dynamics are reasonably well understood, there is a lack of knowledge with regard to the variability in the fluvial systems. Presented here are the findings from several locations within wadi drainage systems to the west of the Hajar Mountain (United Arab Emirates). The performance of Optically Stimulated Luminescence (OSL) dating using a customised standardised growth curve approach is investigated, showing that this approach allows reliable determination of ages by reducing the machine time required. Three main periods of fluvial activity are observed at 160-135 ka, 43-34 ka and ca. 20 ka. Further ages fall into the latest Pleistocene and late Holocene. Interestingly, none of the ages coincide with major wet periods in SE Arabia, identified in stalagmites and by the deposition of lake sediments. It is shown that fluvial activity was partly contemporaneous (within the given time resolution) with phases of aeolian deposition and was almost continuously, but likely sporadically, during the Mid-Late Pleistocene. This highlights the need for regionally defined palaeoenvironmental records in order to fully understand the response of dryland systems to long-term climatic change.

Abstract

Die seit zwei Jahrzehnten in der Ile-de-France durchgeführten präventivarchäologischen Operationen liefern zahlreiche Informationen zu den quaternären Sedimentformationen, die dem letzteiszeitlichen Maximum (LMG) vorausgehen. Soweit dies möglich war, wurden sie mit digitalisierten Datierungen gekoppelt. Die Beobachtungen waren indessen kontrastiert je nachdem, ob sie äolische oder fluvatile Ablagerungen betrafen. Die Daten von den Terrassen und den Tälern der Seine sind insgesamt recht mager. So ist das Ablagerungssystem der Alluvialdecken im Seinetal trotz interessanter Beobachtungen noch nicht erfasst. Nur für den Sektor des Zusammenflusses von Seine und Yonne liegt für die sechs jüngsten Terrassen (MIS 12 à MIS 2 – Marine Isotopic Stage) eine zuverlässige chronostratigraphische Sequenz vor. Einige dieser Terrassen haben paläolithische Siedlungsschichten geliefert. Im Marnetal erlaubt die kürzlich veranlasste Untersuchung der Terrassen es ein erstes Organisationsschema der drei jüngsten Terrassen (MIS 7 à MIS 2) vorzuschlagen; zwei von ihnen lieferten paläolithische Fundplätze. Die äolischen Formationen der Ile-de-France bedecken die Plateaus und Hänge. Abgesehen von einer Sequenz, deren sedimentäre Bilanz die vier letzten glazialen und interglazialen Zyklen (MIS 10 bis MIS 1) deckt, dokumentieren die Daten vor allem, doch uneinheitlich, die letzte Eiszeit (Weichsel) und deren klimatische Schwankungen (MIS 5d bis MIS 2). Spuren des Alt-Mittel- und frühen Jungpaläolithikums sind zahlreich., For the past two decades, preventive archaeology provides datas on Quaternary formations prior to the LGM (Last Glacial Maximum) in the Ile-de-France region. Whenever possible, these researchs are coupled with dating analysis. However, the observations are contrasted according to whether they concern eolian-colluvial or fluvial sedimentary formations. The new data collected on the Pleistocene fluvial terraces of the Seine basin are generally sparce. For example, the terrace system of the Seine valley is currently unknown despite the relevance of some observation points. Only the Seine-Yonne confluence provided relevant chronostratigraphic data regarding the six most recent terraces (MIS 12 to MIS 2 - Marine Isotopic Stage). Some of which have provided Paleolithic levels. In the Marne valley, the study of the terraces system started recently and allows to propose a first scheme for the three most recent terraces (MIS 7 to MIS 2); two of them have yielded Palaeolithic sites. In Ile-de-France, aeolian-colluvial deposits cover the plateaus and their slopes. With the exception of one sequence whose sedimentary budget extends over the last four glacial-interglacial cycles (MIS 10 to MIS 1), the others document mainly, but unequally, the last Weichselian stage and its climatic oscillations (MIS 5d to MIS 2). Numerous Paleolithic remains have been recognized in these last sedimentary formations., Les opérations réalisées en archéologie préventive depuis deux décennies génèrent en Ile-de-France, une information sur les formations sédimentaires quaternaires antérieures au Dernier Maximum Glaciaire (DMG). Couplée lorsque cela a été possible à des datations numériques, les observations sont cependant contrastées selon qu’elles intéressent les couvertures éo-colluviales ou fluviatiles. Les données nouvelles recueillies sur les terrasses dans les vallées du bassin de la Seine, sont dans l’ensemble minces. Ainsi actuellement, le système d’étagement des nappes alluviales dans la vallée de la Seine n’est pas connu malgré la pertinence de quelques points d’observation. Seul le secteur de la confluence Seine-Yonne bénéficie d’une information chronostratigraphique robuste pour les six terrasses les plus récentes (MIS 12 à MIS 2 – Marine Isotopic Stage), dont certaines ont livré des niveaux d’occupation du Paléolithique. Dans la vallée de la Marne, l’étude des terrasses a été initiée récemment et permet de proposer un premier schéma de leur étagement pour les trois plus récentes (MIS 7 à MIS 2) ; deux d’entre elles ont livré des sites du Paléolithique. Les formations éo-colluviales d’Ile-de-France recouvrent les plateaux de la région et leurs versants. à l’exception d’une séquence dont le bilan sédimentaire couvre les quatre derniers cycles glaciaire-interglaciaire (MIS 10 à MIS 1), les autres témoins documentent surtout, mais inégalement, le dernier glaciaire (Weichselien) et ses oscillations climatiques (MIS 5d à MIS 2). Les vestiges du Paléolithique inférieur moyen et supérieur ancien y sont récurrents. .

Abstract

International audience; L’aménagement d’une zone d’activités sur la commune de Dhuisy en Seine-et-Marne, au lieudit "Les Effaneaux" a entraîné la réalisation d’un diagnostic archéologique sur une surface de 57 ha. Des vestiges archéologiques de différentes périodes y ont été découverts, dont de nombreux attribuables au Paléolithique moyen. Ces derniers ont été retrouvés sur de vastes surfaces au sein de stratigraphies lœssiques du Pléistocène. Cette contribution présente le contexte chrono-stratigraphique, des éléments de datation radiométriques et les caractéristiques typo-techniques des industries lithiques de Dhuisy dans le contexte du nord de la France. Les modalités d’identification et de caractérisation en diagnostic d’ensembles enfouis profondément sur de grandes surfaces sont aussi discutées.

Abstract

The specific aim of the study was to investigate how four adjacent geomorphological systems – a lake, a dune field, a small alluvial fan and a slope system – responded to the same impacts. Lake Tresssee is a shallow lake in the North of Germany (Schleswig-Holstein). During the Holocene, the lake's water surface declined drastically, predominately as a consequence of human impact. The adjacent inland dune field shows several traces of former sand drift events. Using 30 new radiocarbon ages and the results of 16 OSL samples, this study aims to create a new timeline tracing the interaction between lake and dunes, as well, as how both the lake and the dunes reacted to environmental changes. The water level of the lake is presumed to have peaked during the period before the Younger Dryas (YD; start at 10.73 ka BC). After the Boreal period (OSL age 8050 ± 690 BC) the level must have undergone fluctuations triggered by climatic events and the first human influences. The last demonstrable high water level was during the Late Bronze Age (1003–844 cal. BC). The first to the 9th century AD saw slightly shrinking water levels, and more significant ones thereafter. In the 19th century, the lake area was artificially reduced to a minimum by the human population. In the dunes, a total of seven different phases of sand drift were demonstrated for the last 13,000 years. It is one of the most precisely dated inland-dune chronologies of Central Europe. The small alluvial fan took shape mainly between the 13th and 17th centuries AD. After 1700 cal. BC (Middle Bronze Age), and again during the sixth and seventh centuries AD, we find enhanced slope activity with the formation of Holocene colluvia. [ABSTRACT FROM AUTHOR]

Abstract

Tin is an essential raw material both for the copper–tin alloys developed during the Early Bronze Age and for the casting of tableware in the Medieval period. Secondary geological deposits in the form of placers (cassiterite) provide easily accessible sources but have often been reworked several times during land‐use history. In fact, evidence for the earliest phase of tin mining during the Bronze Age has not yet been confirmed for any area in Europe, stimulating an ongoing debate on this issue. For this study, a broad range of methods (sedimentology, pedology, palynology, anthracology, OSL/14C‐dating, and micromorphology) was applied both within the extraction zone of placer mining and the downstream alluvial sediments at Schellerhau site in the upper eastern Erzgebirge (Germany). The results indicate that the earliest local removal of topsoil and processing of cassiterite‐bearing weathered granite occurred already in the early second millennium BC, thus coinciding with the early and middle Bronze Age period. Placer mining resumed in this area during the Medieval period, probably as early as the 13th century AD. A peak of alluvial sedimentation during the mid‐15th century AD is probably related to the acquisition of this region by the Elector of Saxony and the subsequent promotion of mining.

Abstract

International audience; In 2013 and 2015, two 8-m-thick loess sequences with palaeosols were excavated in the lower Saône River valley in two sites 20 km away. At Quincieux, the sequence developed on a low terrace of the Saône River shows a lower palaeosol complex with frost wedges, laminated silts including sparsed blocks from the Alps, a median palaeosol or brownish horizon, gray clayey loams with sandy beds, massive loess and a Holocene topsoil complex. At Lyon-Apollinaire, the sequence leaned on the southern relief surrounding the Vaise Plain shows a unique 6-m-thick palaeosol complex eroded at the top and overlaid by massive to laminated fine gray loamy sands cut off by modern constructions. Conversely to the little evidence of human presence in Quincieux, faunal remains have been found in all palaeosols. However, only the oldest palaeosol of Quincieux was partially excavated in 2014. Multi-indicator samplings have been performed to reconstruct the chronological, pedological and environmental contexts of human occupations. 14C ages obtained at the base of gray loams in both sites yield similar ages of 18 ka. OSL and 14C ages obtained in the median brownish horizon of Quincieux are coherent around 20 ka. Conversely, those of the lower palaeosol are more variable between 27 and 40 ka and remain to be discussed. Ages obtained at Lyon-Apollinaire are coherent and reveal that the base and the top of the palaeosol complex correlate with the lower palaeosol and median brownish horizon of Quincieux respectively. Local conditions – slope context away from the alluvial plain – could explain such a difference. The comparison of these two sequences, unique for the lower Saône River valley, with those of northern France is not straightforward.; En 2013 et 2015, deux séquences loessiques de 8 m d'épaisseur avec paléosols ont été mises au jour dans la basse vallée de la Saône sur deux sites distants de 20 km. La séquence de Quincieux, développée sur une basse terrasse de la Saône, montre un paléosol inférieur complexe à fentes de gel, des limons laminés avec des blocs d'origine alpine dispersés, un paléosol ou horizon brunifié médian, des limons argileux gris à lits sableux, des loess massifs et un dernier sol complexe, holocène. La séquence de LyonApollinaire, adossée au relief sud entourant la plaine de Vaise, montre un unique paléosol complexe (6 m) au sommet érodé, surmonté de sables fins, limoneux, gris, massifs à lités, tronqués par des aménagements contemporains. Les restes de faunes y sont peu nombreux à la différence de ceux, avec traces humaines, présents dans les paléosols de Quincieux mais dont seul le plus ancien a fait l'objet d'une fouille partielle en 2014. Des échantillonnages multiindicateurs ont été réalisés pour reconstituer les contextes chronologique, pédologique et environnemental des occupations humaines. Les dates 14 C obtenues à la base des sableslimoneux gris des deux séquences fournissent un âge similaire de 18 ka. Les différents âges obtenus (OSL et 14 C) dans l'horizon brunifié médian à Quincieux sont cohérents autour de 20 ka. En revanche, ceux du paléosol inférieur montre une variabilité plus importante entre 27 et 40 ka sujette à discussion. Pour LyonApollinaire, les datations obtenues, cohérentes, indiquent la complexité du paléosol dont la base et le sommet peuvent se corréler respectivement au paléosol inférieur et à l'horizon brunifié médian de Quincieux. Les condi tions stationnelles-contexte de versant éloigné de la plaine alluviale-pourraient expliquer cette différence. Ces séquences, uniques pour la basse vallée de la Saône, sont plus difficilement comparables avec celles du nord de la France.
